---> What conserved quantities follow from gauge symmetries?#​ 
- 
-Using [[theorems:​noethers_theorems|Noether'​s first theorem]] we find that the conserved charges that would follow from invariance under gauge transformations are identically zero.  This is shown, for example, in section 3.4.1 [[http://​math.ucr.edu/​home/​baez/​classical/​texfiles/​2005/​book/​classical.pdf|here]]. ​ 
- 
-However, using Noether'​s second theorem we can derive relations between our equations of motion, that are known as Bianchi identities. ​
